sure but it's not "/usr/bin/true" of which you might have different versions over
the lifespan of a distro through its updates
(e.g. you can connect gdb to a process that got updated on disk later and still get the right answers)
the disinction of having the "/.build-id/" prefix versus just the code is not a huge difference
(so all the things you can do with just the number you can do with the prefix added as well)
